Boolean operations in Sverchok
To perform Boolean Operations in Sverchok you have three alternatives:

Using CSG Boolean Node: It is pretty slow and sometimes produces not watertight meshes and ugly topology. Also it has some limitations, please check the Warnings section of the nodes documentation

Use a Exec Node Mod to apply standard Blender Boolean modifiers to created objects check this comment: This option is pretty simple but requires a little of coding.

Use the Solid Nodes, that require FreeCad, to perform the operations more info here: Once you have installed the dependencies this should be the easiest and more robust solution
